Respuesta :

Answer:

accurate and precise

Explanation:

Given:

      True value  = 10.4 grams

   Measured values = 10.2 grams, 10.4 grams, 10.3 grams, 10.4 grams, and 10.5 grams.

Solution:

To a very reasonable extent, the values measured given are accurate and precise.

Accuracy is the nearness of the measured value to the true value. We can see that the measured value would have a mean of 10.36grams which is very close to the true value on approximation.

Precision is the ability to repeat a given set of values from a measurement. The measured values are quite precise.
